Premium Australian wild prawns deserve minimal interference — 4 minutes on the grill with garlic, butter, and lemon.
Split prawns down the back without cutting through — remove the dark vein.
Mash butter with garlic, chilli, lemon zest, half the parsley, salt and pepper.
Heat a heavy grill pan (or BBQ) to high. Place prawns cut-side up and spoon over half the butter.
Grill 2 min, flip, grill 2 min more — just until the shells are pink.
Transfer to a serving platter. Dot with remaining butter. Shower with parsley and lemon juice.
Serve immediately with crusty bread to mop up the butter.
McLaren Vale Fiano or a crisp Margaret River Semillon-Sauvignon Blanc.
